Is Your Yukon's Horn Failing?
A non-working horn is a common issue on older trucks like the 1992-1997 GMC Yukon. Usually, the problem is simple to diagnose. The most common symptoms include a completely silent horn, a weak or strange sound, or the horn blowing a fuse every time you press the button.
Common Failure Symptoms
| Symptom | Possible Cause |
|---|---|
| No Sound at All | Blown fuse, bad relay, failed horn switch in the steering column, or both horns have failed. |
| Weak or "Sick" Sound | One of the two horns (either high or low note) has failed, leaving the other to work alone. This can also be caused by corrosion on the electrical connectors or a bad ground connection. |
| Horn Blows Fuse Instantly | This indicates a short circuit. The short could be in the horn assembly itself or in the wiring, which can become brittle and frayed over time. |
| Horn Works Intermittently | Often caused by a failing relay, a loose connection, or a worn contact in the steering wheel horn pad. |
Choosing the Right Aftermarket Horn
When shopping for a new horn, you'll find several options. Original Equipment (OEM) horns from a dealer are an option, but they are often expensive. Aftermarket horns provide the same function and fit at a much lower cost, making them a popular choice for these Yukons.
Pro Tip: Before buying a new horn, always check the 15A or 20A horn fuse and the horn relay in the under-hood fuse box. You can test the relay by swapping it with an identical one from the same fuse box (like the A/C relay) to see if 🎬 Watch this quick guide on testing your horn fuse and relay. the horn starts working.

A Note on Steering Column Issues
On this generation of GM trucks (GMT400), a faulty horn can sometimes be caused by issues inside the steering column, like a bad horn contact or a failing clockspring. Symptoms like the horn going off when you turn the wheel point directly to this area. While replacing the horns themselves is easy, steering column work is more complex and involves removing the airbag. This should only be attempted if you are confident in your skills or by a professional mechanic.
Frequently Asked Questions
Where is the horn located on a 1992-1997 GMC Yukon?
These trucks have two horns. One is typically located behind the grille, often near the center radiator support. The other is often found behind the passenger-side headlight assembly. You may need to remove the grille or headlight to access them.
Do I need to replace both horns?
Not necessarily. If one horn has failed, you can replace just that one. However, they are sold as high-note and low-note specific parts. If you replace a failed low-note horn with a new high-note horn, the sound will be off. It's often a good idea to replace them in pairs to ensure a proper sound and since the other original horn may not be far from failing as well.
Is replacing the horn a difficult job?
No, replacing the horn assemblies is a very easy job. It usually involves removing a single 10mm nut and unplugging an electrical connector. Accessing the horn is the most challenging part, but it is still a beginner-friendly task that requires basic hand tools.
🎬 Follow this step-by-step video to replace your GMT400 horn.Why does my horn blow the fuse when I press it?
A fuse that blows immediately indicates a short circuit in the system. This could be due to an internal failure within the horn itself or damaged wiring that is touching the metal frame of the truck. Unplug both horns and try a new fuse. If it doesn't blow when you press the horn button (the relay will just click), the short is in one of the horn units. If it still blows, the short is in the wiring before the horns.
